YPONOMEUTID>E. DEPRESSARIA. 197 



Gknus CCCXIX. — Depuessarta, Houortli. 



Paljii long, slightly divaricating, curved upwards and backwards, the second 

 joint clothed with very long broad scales, the basal with short ones, and the 

 apical appearing naked, very slender and attenuated : maxillw short and 

 thick, with scales in front. Antenna remote, inserted on the crown, slender, 

 simple : head wide, clothed with broad scales : eyes small : thorax robust : 

 wings incumbent during repose ; anterior linear, lanceolate ; posterior short 

 and broad : body broad and depressed, with a few tufts of hair on the sides 

 and at the tip, the apex in the males rather attenuated, sliglitly recurved, 

 with a small tuft : /f^i rather short. Larva generally found on umbellife- 

 rous flowers, and changing to a pupa within the stalks. 



The broad flattened abdomen of the insects of this genus, and 

 horizontally incumbent wings, at once indicate its distinction from 

 the other genera of this family ; the recurved palpi existing in several 

 others : in habit the insects differ, inasmuch as they are usually 

 found, in the larva state, subsisting on the flowers of umbelliferous 

 plants, and the pupa is found within their stalks : they are generally 

 autumnal. 



A. Anterior wings rounded behind, the disc generally with interrupted dark 

 streaks, sometimes dotted: — Pinaris, Hiibner.

Anterior wings pale griseous, with numerous approximating black streaks on 

 the disc, and a whitish central dot, behind which is a very much angulated 

 pale streak ; the hinder margin is also pale, and has a row of large fuscous 

 spots : posterior whigs pale fuscous, with pale yellowish cilia. 



Caterpillar feeds on the Cow-parsnip {Heracleum sphondylium) and other um- 

 belliferous plants : it is pale, with black dots and a yellowish head : the 

 pupa is found in the stalk, and the imago appears in July. 



Not uncommon in June on umbelliferous plants throughout the 

 metropolitan district in the larva state, especially at Darenth wood ; 

 frequent also in the New Forest and in Devonshire.
